Technical Frequently Asked Questions

What can be connected to the RFC-4800 IO-Link contactless angle sensor?

It can be connected to Novotechnik M12 connectors and cables and Novotechnik rotary sensor positioners (magnets).

How do I order the RFC-4800 IO-Link contactless angle sensor?

The order code has six fields: mechanical version, digital interface, resolution, interface, parameters, and connection. For example, RFC-4852-214-A11-252 is the version with round hole mounting, digital interface, 14 bits, IO-Link with one clockwise incrementing position, and a 1 m unshielded 4-pole cable. All the options for each field are available in the order code configurator on this page.

Under what conditions does the RFC-4800 IO-Link contactless angle sensor operate?

Operating temperature: -40 … +105 °C, -25 … +85 °C (M12 connector). Protection: IP67 / IP68 / IP69, IP67 (M12 connector).
